The combined measuring device "ABO-63" (School) has been produced since the beginning of 1963. The combined measuring device `` ABO-63 '' (School) is designed to measure direct and alternating voltage from 0 to 1000 volts, direct and alternating current from 0 to 500 mA, as well as resistance from 1 Ohm to 2 Mom. Manual switching of measurement modes by inserting a phase probe into the appropriate socket. There is a switch for measuring constant or variable values "u200b"u200band a regulator for aligning the end mark on the scale when measuring resistance. Accuracy class 2.5. The power supply for the device"™s ohmmeter consists of 3 elements: FBS-0.25, 1.3-FMC-0.25, 332 or 336. In 1977, the device was updated to receive a case made of unbreakable plastic and a new dial indicator. The device was without a cover like the previous one, but it had a gray iron case with blue color, with a closing lid. The device was named as "ABO-63" (Training). ,null,ru,null,null,null,null
